Definitions
- Known spinning pumps of this type are used in the chemical fiber industry in the manufacture of threads from solutions or melts of a wide variety of substances, such as a solution of cellulose acetate in acetone or melts of polyester, e.g. Polyethylene terephthalate, or of polyamide, e.g. Polyamide-66, used.
- this solution (the spinning liquid) is passed under a pressure of, for example, 20 bar through an - inner - inlet channel of the spinning pump block and the corresponding, flush - inner - channel of the Spinning pump guided into the gear plate or plates of the spinning pump, passed there between the teeth of meshing gears and then under a pressure of, for example, 85 bar through - inner - outlet channels of the spinning pump, which are aligned with corresponding - inner - channels of the spinning pump block, again Spinning pump block fed.
- melt spinning is carried out in the same way, but in this case considerably higher pressures have to be used to convey the spinning liquid, ie the melt, since such melts have a relatively high viscosity.
- the pressure of the melt can be, for example, 40 bar in the inlet channel and, for example, 300 bar in the outlet channels.
- An improvement in the aforementioned sealing cannot be achieved either by increasing the number of fastening screws or increasing the surface pressure (by reducing the contact area between the base plate of the spinning pump and the spinning pump block) or by using flat seals between the base plate of the spinning pump and spinning pump block.
- the invention is therefore based on the object to provide a spinning pump of the type mentioned which, when used, enables such a good seal on the surface on which the base plate of the spinning pump and the connecting surface of the spinning pump block touch that even when using the highest pressures the spinning liquid cannot escape this liquid from the inlet and / or outlet channels in the area of that surface.
- a spinning pump of the type mentioned which, when used, enables such a good seal on the surface on which the base plate of the spinning pump and the connecting surface of the spinning pump block touch that even when using the highest pressures the spinning liquid cannot escape this liquid from the inlet and / or outlet channels in the area of that surface.
- the invention is based on the following principle: The power flow generated by the mounting screws is redirected with / in the adapter part so that it comes into effect in the - smaller - area of the spinning pump in which the spinning liquid flows (mostly mainly in the middle), i.e. where the Hydraulic forces acting on the pressure of the spin fluid and could cause a bulging - as described above.
- cap screws can be used as fastening screws.
- These through bores preferably allow a - slight - play between the bore walls and the fastening screws.
- the fastening screws are screwed into internally threaded holes in the spinning pump block.
- a hardened steel is preferably used as the material for the adapter part, the various plates of the spinning pump and the spinning pump block.
- Fig. 1 shows schematically a spinning pump according to the invention.
- the base plate 4, the gear plate 5 and the cover plate 6 of the spinning pump 1 consist of hardened steel and are connected to one another by means of screws (not shown in FIG. 1).
- the spinning pump 1 also has an - inner - inlet channel 8 and four - inner - outlet channels 9 for the spinning liquid, which lead through the base plate 4 into the gear plate 5.
- the inlet channel 8 leading through the base plate 4 into the gear plate 5 is aligned with the inlet channel 8 of the spinning pump block 2, and the outlet channels 9 leading through the base plate 4 into the gear plate 5 are respectively aligned with the corresponding outlet channels 9 of the spinning pump block 2.
- the spinning pump block 2 is also made of hardened steel.
- the spinning pump 1 is of round design, that is to say that it is essentially cylindrical.
- the spinning pump 1 has a diameter of 92 mm.
- the through holes 12 leave a play of 0.5 mm between the walls of the through holes 12 and the fastening screws 3.
- the fastening screws 3 are screwed into internally threaded bores 13 in the spinning pump block 2.
- the depth of the groove 16 is 19 mm; the width of the groove 16 is 3 mm.
- the bore 14 in the adapter part 15 (for the drive shaft 7 and the coupling 17) is arranged round and centrally through the adapter part 15 and has a diameter of 30.6 mm.
- the adapter part 15 has a height of 27 mm, and the groove 16 is at a distance of 10 mm from the screwing surface of the adapter part 15 to the cover plate 6 of the spinning pump 1.
- the inside diameter of the groove 16 is 54 mm.
- the invention is of course not limited to round spinning pumps, but can be applied to spinning pumps of any design.
